Excitation of non-quark degrees of freedom in N*
B. Golli, P. Alberto, M. Fiolhais
We study the contribution of glueball and sigma-meson degrees of freedom to nucleon excited states in the framework of a chiral version of the chromodielectric model. We have found…

Bojan Golli
We describe how the non-local regularization can be implemented in the calculation of solitons in the Nambu Jona-Lasinio model as well as in the equivalent linear sigma-model. We i…
